At the time, as in search of an effective free cooling Facebook and Google servers are transported in cold countries, Microsoft went the other way and decided to place their data centers under water. The initiative was named Project and Natick, in the opinion of the Corporation engineers have good prospects. Energy for the functioning of a complex turbine generates the generator, you also get significant savings on maintenance. Cooling happens by itself, because the server is completely under water. The company has already successfully tested the first prototype under the name Leona Philpot, who was at the bottom of the sea off the coast of California 105 days (August to November 2015). The experiment has allowed to verify the viability of the system. According to creators, having adjusted mass production of these modules, within 90 days Microsoft will be able to take completed orders to customers. This is faster than 2 years that are required for the construction of the data center on the earth’s surface. Each underwater unit is able to last up to 20 years with a mandatory upgrade computer systems every 5 years.
